120A is a behemoth of a class, fluid dynamics is often some of the most technically difficult math you will see in your coursework, so I know that Professor Helgeson did his best with an already confusing and hard subject. I appreciated that he was willing to meet me for extra tutoring, because I really struggled in exam-taking for this class.

120A Mid lectures at best. Easy midterm but impossible final worth 40%. One of the problems we never once did anything related on a HW so no practice. I stg he picks HW problems via throwing at a dartboard, not whats covered in lecture. So many errors in notes, HW solutions, even exam questions. I feel like I barely learned anything. Underwhelming

A professor who tries his best but falls short in more fields than he succeeds. Lectures are jam packed with material in too short of a time frame that it feels like he's just regurgitating discombobulated information at you with little to no coherency. Assignments do not align with lectures and textbook felt close to useless. Bad at emails.

I do sincerely think while he makes mistakes here and there, he is the best professor I have ever taken in UCSB so far and will be one of them by the graduation.

Grades fairly hard but the class ends up having a nice curve, so it is passable. He told us that he did "very bad" on his first chemical engineering test, but he got a C! He also claims to give a lot of partial credit on tests, but I didnt experience that first hand. Overall, do the homework and put in the effort to understand it and you'll be fine

Tough class due to lots of problem sets, relatively difficult exams and it being the first real ChE class. Good lecturer, made some mistakes here and there but really helpful in office hours. Other than being super smart, he's very nice and not intimidating. Utilize office hours!!!
